The Jackson Customers Service Mailing Processing Center will be moved to Detroit in less than a year, the Postal Service said last week.

Postal officials announced in February there would be no changes to the retail operations or the business mail entry unit operations and that about 14 postal service workers from Jackson would be transferred to other locations in the Detroit district, saving about $2 million annually.

John Marcotte, president of the Michigan Postal Workers Union, said the plan will result in lost revenue and slower service for customers.

“In today’s environment, who is slowing down?” he said. “This is absolutely irresponsible of the Postal Service.”

Marcotte said these smaller processing facilities, like the one in Jackson, have saved the Postal Service money in transportation and fuel costs. He said the Postal Service is not computing these costs into its calculations.

This is not true, said Ed Moore, spokesman for the Postal Service’s Detroit district. With moving the Jackson operations to Detroit, officials expect a net savings of about $298,000.

In total, 230 smaller postal offices will have their services consolidated with larger offices, officials said. They believe the restructuring will save the agency about $2 billion annually.

The first phase of activities will result in up to 140 consolidations, including Jackson, through February.

Approximately 5,000 employees will begin receiving notifications next week related to consolidating and other efficiency-enhancing activities to be conducted this summer.
